fail to set target temperature after HA upgrade to 2024.8

[eddysteurs]

*After upgrading HA to 2024.8 it fails to set the target temperature to different value. On the HA temperature card (and climate entity) it does change the value but it does not flow to the actual device. So on next refresh from all sensors it is back on the original value. When setting it via the temperature card (or an automation) is gives error 'Failed to perform the action climate/set_temperature. '<' not supported between instances of 'float' and 'NoneType''
